Ruschel, 27, was one of only six survivors on the plane that crashed into the mountains near Medellin, Colombia. The disaster killed 71 people, including almost all of the Chapecoense team, directors and staff.
Goalkeeper Follman, one of Ruschel's best friends in the team, also survived, but had part of his leg amputated. He was transferred on Saturday morning via air ambulance from Sao Paulo to a hospital in the club's home city in southern Brazil.
"I don't remember anything about the accident,' Ruschel said at the Arena Conda, the club's stadium in Chapeco.
"When they told me what happened it seemed like a dream, a nightmare. Little by little they've been telling me what happened and I'm starting to understand.
"I try not to speak of the accident, I avoid the news, but from the little I've seen I think it was greed on the pilot's part."
The pilot of the Bolivian-run LAMIA plane has been accused of taking off without enough fuel for the flight. Bolivian authorities suspended the airline's operating license and replaced the management of its aviation authority to ensure a transparent investigation.
Ruschel promised to return to Colombia and treat his doctors there to one of the hearty barbecue meals famous in southern Brazil.
He also pledged to visit every one of the families of his compatriots who died before returning to the small town of Chapeco and continuing with the physiotherapy he needs to get fit again.
"As a lesson, this tragedy teaches that you have to keeping living," he said. "Take advantage of some things and do good for others.
"When I got here today I had the sensation that I was coming home. I promise to give lots more happiness to this team. With a lot of effort and hard work I am going to be back playing again soon."
